The Rise of Sexually Transmitted Ringworm: A Growing Public Health Concern
Health officials are sounding the alarm over a concerning outbreak of a contagious fungal skin infection, specifically a strain known as Trichophyton mentagrophytes genotype VII (TMVII). Whereas often referred to as “ringworm,” despite not being caused by a worm, this fungal infection is increasingly being spread through sexual contact, prompting a unique public health response.
What is TMVII and Why is it Different?
TMVII is a recently emerged fungal strain causing severe dermatophyte infections. Unlike typical cases of ringworm, jock itch, or athlete’s foot, this strain is demonstrating a pattern of transmission linked to sexual activity. The Centers for Disease Control and Prevention (CDC) notes that TMVII can be easily mistaken for other skin conditions like eczema or psoriasis, requiring laboratory culture and DNA sequencing for accurate diagnosis.
Pro Tip: Don’t self-diagnose. If you notice a round, itchy, or irritated rash, especially in the genital area, consult a healthcare professional immediately.
The Outbreak: Minnesota Leads the Way
Minnesota is currently experiencing the largest known outbreak of sexually transmitted TMVII in the United States. As of February 17, 2026, the Minnesota Department of Health (MDH) has reported more than 30 confirmed or suspected cases in the Twin Cities metro area since July 2025. The first U.S. Case was identified in New York City in June 2024, with sporadic cases appearing in other major cities.
The MDH established an enhanced surveillance system to identify cases after several individuals sought care and provided information about potential contacts. This proactive approach highlights the importance of tracking and understanding the spread of this unique fungal infection.
Symptoms and Diagnosis
The primary symptom of TMVII infection is a round, red, irritated rash that can be itchy and painful. This rash often affects the genitals, perianal area, buttocks, thighs, and abdomen. Diagnosis can be challenging, as the symptoms can mimic other conditions. Clinicians are advised to initiate treatment based on symptoms and risk factors, rather than waiting for lab confirmation.
How Does TMVII Spread?
TMVII spreads through direct skin-to-skin contact, including sexual activity. The fungus can too spread via contaminated objects and surfaces, such as shared towels or in communal bathing facilities. This highlights the importance of practicing good hygiene and avoiding sharing personal items.

Treatment and Prevention
While routine cases of ringworm often respond to over-the-counter antifungal creams, TMVII frequently requires antifungal pills for complete resolution. Individuals with symptoms should avoid close skin-to-skin contact and refrain from sharing personal items. Thoroughly washing linens and towels on high heat and sanitizing bathing areas are also crucial preventative measures.
Sexual partners of individuals diagnosed with TMVII should be informed and evaluated for symptoms.
Future Trends and Considerations
The emergence of TMVII signals a potential shift in the landscape of sexually transmitted infections. Increased awareness among healthcare providers and the public is critical for early detection and effective treatment. Further research is needed to understand the factors driving the spread of this fungal strain and to develop more targeted prevention strategies.
The unique transmission pattern of TMVII – through sexual contact – suggests a need for public health messaging that specifically addresses this route of infection. This may involve incorporating information about TMVII into existing sexual health education programs and promoting safe sexual practices.
FAQ
Q: Is TMVII a serious infection?
A: While often treatable, TMVII can cause persistent and uncomfortable symptoms. Left untreated, it may lead to scarring or secondary bacterial infections.
Q: Can I get TMVII from a public shower?
A: It’s possible, as the fungus can spread through contaminated surfaces. Avoid walking barefoot in public showers and avoid sharing towels.
Q: What should I do if I think I have TMVII?
A: Consult a healthcare professional immediately for diagnosis and treatment.
Q: Is TMVII common?
A: TMVII is a recently emerged strain, and outbreaks are currently limited to specific areas. Still, the number of cases is increasing, raising public health concerns.
